Introduction

 
Over four billion years ago, rocks were created and became an important part of
the Earth's surface. The rocks might have been part of a mountain or a river
bank. They might have seen the dinosaurs that roamed the Earth. Now, you have
become a Rock Detective and need to go out and file a report on one of these
missing rocks such as Sally Sedimentary, Ivan Igneous, and Mikey Metamorphic
Rock. You will need to find out where they can be found and how they got there.
You will be using all your skills as a detective. Happy hunting.
